The IRS is warning taxpayers to be on the alert for e-mails and phone calls which claim to come from the IRS or other federal agencies and which mention their tax refund or economic stimulus payment. These are almost certainly a scam whose purpose is to obtain personal and financial information — such as name, Social Security number, bank account and credit card or even PIN numbers — from taxpayers, which can be used by the scammers to commit identity theft. The e-mails and calls usually state that the IRS needs the information to process a refund or stimulus payment or deposit it into the taxpayer's bank account. The e-mails often contain links or attachments to what appears to be the IRS Web site or an IRS “refund application form.” However genuine in appearance, these phonies are designed to elicit the information the scammers are looking for. Be aware that the IRS does not send taxpayers e-mails about their tax accounts.
